title: A fast and simple approach to the quantitative evaluation of fibrinogen coagulation.
abstract: Fibrinogen is essential in the intrinsic and extrinsic blood coagulation process. Inhibition of fibrinogen aggregation could lead to anticoagulation effects. The availability of methods for easy quantitative evaluation of the coagulation process is critical to studying coagulation and its inhibition. A commonly used method is UV-Vis absorbance (405 nm) detection by a micro-plate reader. However, because of the heterogeneous nature of the resulting mixture in a coagulation process, transmission-based optical measurements give large variations. Herein, a very simple and easy method is developed for the quantitative measurements of the coagulation process. The method was validated using three known thrombin inhibitors: 4-(2-aminoethyl) benzenesulfonyl fluoride (IC50: 0.01 mM), p-amidinophenyl methanesulfonyl fluoride (IC50: 0.18 mM) and PMSF (IC50: 0.23 mM).
